• The radial flow of a thin liquid film is studied experimentally. The liquid film was obtained by a water discharge from the thin cylindrical opening formed by a circular nozzle and a flat plate. The film thickness was measured by means of a point gauge method. The experimental results about laminar flow are compared both with the theory of Watson and with the approximate solution for a film flow formed by a water jet falling vertically onto a horizontal plane, by using an equivalent length of opening instead of a radius of water jet. About the liquid film in which the transition from laminar to turbulent flow occurs, the approximate solution for turbulent region is compared with experimental results.
